I would definitely pick up a tank from petco right now. You could get a glass versa top and then order a Finnex Stingray 20in light from Co-op. I have the 24in and it's nice. With that light she could even add some stem plants. I wouldn't want the hoods that use bulbs personally. I'd rather have the LEDs.
I see that others mentioned Eheim heaters and I've also had good experiences with them!
If she doesn't have a timer already, you could pick up the Kasa smart plug from Co-op too. I'm forgetful so having a timer is super helpful for me. 😅
